In this task you will be given a passage and a yes/no question based on the passage. You should answer the question using the information from the passage.
Q: passage: It is useful to note that the mass-center is a fixed property for a given rigid body (e.g. with no slosh or articulation), whereas the center-of-gravity may, in addition, depend upon its orientation in a non-uniform gravitational field. In the latter case, the center-of-gravity will always be located somewhat closer to the main attractive body as compared to the mass-center, and thus will change its position in the body of interest as its orientation is changed.
 question: is center of gravity and center of mass the same?
A: 
No
